Jandy Aqua Pure 700 Issues

[Square Grouper]

5 year old Jandy Aqua Pure 700 system. Stopped making chlorine a couple weeks ago. I found the troubleshooting manual online and went through it. I've pretty much narrowed it down to the front board or Flow/salinity sensor. The front board runs about $275 and the Flow sensor $180. Each is non returnable. I'd really like to narrow the problem down as to not waste $$ on a 50/50 shot and getting the right one. Jandy tech support was no help as my system is not under warranty.

The most aggravating part of this and maybe a clue as to the problem is the salinity reading the machine is showing. It is showing a reading of 13.6 (Waaaay High) but I have tested the water myself and had a pool place test it and I am right at 3.0 where I should be. When try to enter the calibration screen on the unit to calibrate the salinity, it won't adjust.

I appreciate any help!

The flow sensor can be tested with a multimeter for continuity. Remove the wires off the flow switch and test with the pump off and with the pump on. Test the two terminals on the flow switch. If it's reading an opened circuit with the pump off and a closed circuit with the pump on, the flow switch is good. It may be the flow switch wire too. However, continuity can also be tested on the cable.
Once you've verified the flow switch and cable are good, you can short the terminals that the flow switch is connected to the power supply, to simulate a good flow condition.

IF the power supply shows there is no flow, then it's most likely the circuit board.

I don't know how to test just the circuit board to see if its good or not, but this gets one component out of the picture of possible problems.

Sean, Did you mistake the Aqua-pure 700 for an Aqua-rite?

Square, Have you gotten any 3 digit codes on the display? Looking for a 172 or 186. Those are a couple sensor codes. If you are getting 13.6 for salt and have not added that much salt, then i would be pretty sure that it's the sensor.

Pool Clown, you're right. Aqua Pure is the old Chloromatic right? The salinity and flow sensors are built into a single components ensor with the phone plug connector molded into it.
My bad.

Right, but the old Chloromatic (CM2), the sensor plug looks more like a network plug than the Aqua rite's phone looking plug.

Having similar problem with my Jandy 1400. It's showing code 170 (a front board issue or the 120 v is not connected correctly). Since the unit has been working fine for 2.5 years I will assume it is wired properly. I purchased a new board and installed it to no avail. It is still throwing the same code with the new board. Any ideas would be appreciated. We have no authorized service people in Indianapolis.

I'm working on a 170 code right now. I've swapped out a front board, back board, checked the voltages, (what the flow diag says to do) but still has code. Will be back today or tomorrow to replace sensor (my diagnosis, we'll see if im right), and will let you know then what happened.

Update: Changed the flow, temp, salinity sensor and that fixed it. Crazy, those flow sensor have turned out to be a real pain the past year or so.
